Conventional systems include low-efficiency systems that use direct current fluorescent discharge tubes, polarity reversing circuits, stabilizing circuits using resistors, and starting circuits using thermal switches, etc., as well as low-efficiency systems that use DC fluorescent discharge tubes, motor generators, and semiconductors called thyristors called chopper MOs. However, the present invention utilizes a high-voltage transistor that can be connected directly to the train power supply by applying a high-voltage transistor, which is more efficient than the current situation. We provide a method of reverse conversion and lighting using high-frequency power. Streetcars use DC 600V [1F50V] as a power source, but the voltage drop due to the large starting current immediately after the train starts, and it also stops. Sometimes the ratings are even higher.

A rising current is applied through each of the collector windings 21 and 23 on the input side, electromagnetic induction is induced in the pace winding 22 by the transformer action, and zero current is added to the DC bias as an AC bias, which accelerates and saturates. When the point is reached, the electromagnetic induction becomes zero and the current flow stops. Furthermore, the power transistor 9 is completely shut off due to the back electromotive force. The operating point can be varied by changing the AC bias resistance 70 value. pi, pass capacitor 8

In addition, since the stabilizing choke and filament transformer, which are well-known technologies, are not required, the overall efficiency is significantly improved. In general, pushing oscillation is considered to have lower efficiency than push-pull oscillation (Royer circuit). There is a transformer with the above-mentioned specific structure! If used, it has been confirmed that there is no difference from C. It is advantageous in handling because it is small and can be designed with a flat surface.
